TXC04201B Overview
The DS1MX7 is a seven-channel byte-synchronous and asynchronous DS1 mapper. Both SONET and SDH mappings are provided per Bellcore GR-253-CORE (VT1.5) and ITU-T G.707 3-96 (TU-11). A single add/drop Tele Bus is provided that can operate at either 6.48 or 19.44 MHz, which is patible with other TranSwitch devices.
